Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The study is designed to determine whether there are clinical features that can be used as biomarkers to predict whether underlying Alzheimer's pathology is the cause of a speech and language based dementia. The primary hypothesis is that the proportion of patients who test positive for beta-amyloid deposition will vary across different speech and language based dementias.

Investigators

A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
